Answer:
Black soil is formed by the deposition of sediments in river plains and deltas. The sediments are predominantly clay and silt particles. The black colour of the soil is due to the presence of organic matter. The organic matter content in the soil is high, which makes it very fertile. The soil is also very moisture-retentive.
Black soil is very suitable for growing crops such as cotton, rice, wheat, and sugarcane.
